What is the locomotion of a stingray?

Answer 1

The movement of a stingray is accomplished through rajiform locomotion, which generates thrust by undulatory waves passing down the enlarged pectoral fins. The movement is produced by alternate firing activity in the dorsal and ventral muscles from the anterior to posterior ends of the fin.

Answer 2

Stingrays use their large pectoral fins to "flap" and glide through the water. They flap their fins in a wave-like motion to propel themselves forward, much like a bird flapping its wings. Their unique shape and movements allow them to be quite graceful and efficient swimmers in the ocean.
